Subject: [GIT PULL] target: Updates for v3.2-rc1 (round one)
Hi Linus,
The following is the first round of target updates for v3.2-rc1. It's
available directly from kernel.org here:
git://git.kernel.org/pub/scm/linux/kernel/git/nab/target-pending.git for-next
What can I say...? Christoph really outdid himself this round with a
long list of cleanups culminating with the conversion to push the core
completion path out of transport_processing_thread() and into a separate
target workqueue. There are still a number of performance improvements
in the works, most of which at this point will end up being v3.3 items.
Also included are a handful of bugfixes reported by various folks that
are marked for stable@...nel.org, and other various improvements +
removal of legacy code.
The bulk of this series has been posted for review in the last weeks
here:
[PATCH 00/37] target: Updates for v3.2-rc1 (round one)
http://marc.info/?l=linux-scsi&m=131855299419466&w=2
Unfortunately this code has only gotten minimal linux-next testing as
the target-pending.git tree did not return to kernel.org until last
week. I've been able to verify it does not conflict with linux-next
from 20111014, and has been getting some testing in lio-core.git and I'm
content enough for an merge into v3.2-rc1.
For the second round of v3.2-rc1 changes, a new ib_srpt module will be
merged once Roland is happy with the recent review cleanups. There is
still some outstanding non-critical breakage with last rounds conversion
to use errno.h in certain areas that still needs to be addressed, as
well as a active I/O shutdown refactoring that I’m also targeting for
v3.2-rc1.
Thank you,
--nab
